To all whom it may concern:

Be it known that I, ALEXANDER WINTON, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Vertical ExplosiveEngines, of which the following is a specifica tion, reference being hadtherein to the accompanying drawings.

This invention relates to improvements in vertical explosive-enginesespeciallyintended for use in motor-driven vehicles orautomobiles.

One object of my present construction is to permit the ready removal ofany moving portion of the motor through the side of the crank-case andto provide the crank-case with a section or chamber inclosing thedriving-gears for the water-pump and fan of the cooling system andfurther pertains to certain details of construction hereinafterpointwill be explained are attained.

In vertical motor construction as heretofore used two methods of supporthave been employed. In both instances the crank-case has been splithorizontally at the crank-shaft center. One method is supporting themotor from the lower half of the crank-case, which requires the removalof tne heavy cylinders and the disconnecting of all water, gasolene, andcarbureter connections in order to either inspect or remove thoseportions of the j motor which are located within the crankcase, andwhich experience teaches need frequent inspection, and need to beremoved in the event of a necessary substitution of any of the parts,which method is exceedingly diflicult owing tothe weight of the upperportion of the crank-case and the cylinders carried thereby. This makesthe inspection or substitution of a part by a driver when on the roadvery impractical and in many cases impossible. The other method ofsupport is from the upper half of the crank-case, and in this event itis necessary for the person removing the lower half of the crank-case toeither use a pit, or when a pit is not accessi bleas, for instance, whenon the roadrequiring the person removing the lower half to lie upon hisback under the machine. This latter position is awkward and difficult,and when the lower half has been removed the oilalways present in thecrank-case is probably, and, indeed, usually at least partly despecialappliance and at any place.

posited upon the person removing the lower half of the crank-case. Bythe special construction hereinafter shown and described thesedisadvantages are obviated, and the driver is able to readily inspect,adjust, or remove the crank-shaft, the connecting-rods, or the pistonwhile in an upright position at the side of the vehicle, and this canreadily be done by one person without the use of any These advantages ofinspection, adjustment, and removal of the parts of a verticalexplosivemotor are believed to remove the recognized objections to suchform of motor, while all of the inherent advantages thereof remain.

The above recited disadvantages in the method of construction andsupport of a ver ;tical motor have been recognized for years; but so faras I am aware they have not heretofore been overcome by a specialconstruction of the motor, as hereinafter disclosed.

ed out whereby certain advantages which In the accompanying drawings,Figure 1 is .a front end elevation of a motor-frame embodying myinvention and my improved method of support. Fig. 2 1s a side elevationof my improved motor constructlon, showlng the side thereof removed andthe bearings and motor-support in section. Fig. 3 is a detachedsectional view of my improved removable inspection-cap. Fig. 4 is adetail view of the removable cap or cover for the crankcase.

In carrying out this invention the vehicle is provided with suitablelongitudinal beams 1 and with cross-drop motor-supporting frames orbeams 2. These drop beams or frames 2 (of which there will be a suitablenumber to properly and effectively support the motor) are, as shown inFig. 1, of a diverging-U shape, the ends of the said frames 2 beingsuitably connected with the longitudinal beams l of the vehicle-frame.

In my improved motor construction the crank-case has a lower portion 3bolted to the horizontal part 4 of the beams 2 and extends upward to thelower end of the cylinders 5. As shown, one side of the lower portion 3of the crank-case ends in a line vertically over the center of thecrank-shaft 6 and becomes in a sense an immovable portion of thecrank-case in that it is bolted to the dropframe 4 and is not to beremoved so far as the inspection, adjustment, or substitution of any ofthe parts therein is concerned.

From the foregoing it will be observed that the crank-case isconstructed with an open side extending from the lower ends of thecylinders to the horizontal portion of the beam 2, and that thecylinders are supported by the permanent part 3 of the crank-case. Thisopen side of the crank-case is closed by a removable cap or cover 7,which is held in the position shown in solid lines, Fig. 1, by fourbolts 8, and the removable portion 7 carries the caps 9 for the endbearings 10 of the crank-shaft.

By reference to Fig. 1 it will be observed that the lower portion 3 ofthe crank-case is located to one side of the center of the beam or frame2 and practically occupies all of the horizontal portion 4 at that sideof said center, whereas there is considerable space of the horizontalportion 4 outside of the outer edge of the removable cap portion 7. Thisenables the cap portion 7 by the removal of the four bolts beforementioned to be slid sidewise sufficiently to enable it to be removedbodily upward and free of all parts of the motor casting or frame orother parts of the vehicle. When thus removed, the connecting-rodbearings can be readily adjusted or the connecting-rods, together withthe piston 11, removed from the motor through the side of the crank-caseand without disturbing the crank-shaft, since the crank-shaft is locatedat a distance below the lower endof the cylinder 5 to permit suchremoval.

By reference to Fig. 2 it will be noted that the rear end 12 of thecrank-shaft projects through the crank-case and to which exten sion isconnected the fly-wheel 14, and this extension 12 carries the fly-wheelhub 15. A slot 16 receives a transverse projection carried by the disk17, which has projections at right angles upon opposite sides, the otherprojection being carried by the adjacent end of the drive-shaft 18. Thevehicle driveshaft 18 will be connected in any suitable manner with therear driving-axle of the vehicle, and this is not here shown, as it isunnecessary to the understanding of the pres ent invention and has nospecial relation thereto beyond what is readily known and understood bythose skilled in the art. The removable cap portion 7 being removed, aspreviously described, and the crank-shaft turned so that the slot 16 andprojection 17 are in a horizontal position the crank-shaft can bereadily removed by disconnecting the caps 19 of the connecting-rods 20and the removable cap for the center bearing 21 of the crank-shaft.

To still further provide for a quick inspection of the connecting-rodbearings and the portions within the crank-case, the removable capportion 7 is provided with one or more inspection-openings 22, which areclosed by quickly-removable covers 23. The special form of clamp forthese covers here shown consists of a transversely-arranged bar 24,which has its ends adapted to engage openings 25, formed in lugs 26,projecting outwardly from the removable cap portion 7. Passing throughthe center of the bar 24 is a screw 27, adapted to engage a recess 28formed in the cover 23, and the outer end of this screw is provided withan operatingwheel 29. By turning upon the screw the cover will betightly clamped to position. By turning outward or loosening the screwthe bar 24 can be moved endwise to disengage one of its ends from thelug 26, and the cover then removed, the engaging end of the.

bar acting as a fulcrum.

My improved crank-case is provided at its forward end with an extensionor chamber 30, which contains the gearing for the camshaft 31 and thecooling-fan 32. This gearing consists of a pinion 33, fast to thecrankshaft, which meshes with a gear 34, fast to the cam-shaft 31, andthis gear 31 is in mesh with the fan-gear 35. Also in this improvedconstruction the cam-shaft 31 passes longitudinally through the upperend of the crank-case and has its forward end projecting and carrying acrank-arm 36, and this crank-arm 36 is located in a chamber or box 37,which is formed as a part of or suitably clamped to the said extensionor chamber 30, and supported upon this box or chamber 37 is an air-pumpcylinder 38. The pitman or connecting-rod 39 connects the crank-arm 36with the pump-piston 40. The object of this air-pump is to provide apressure-governor for the motor by means of which the driver controlsthe speed of the engine, and therefore the speed of the car, the airfrom the said pump acting upon the motor inletvalves (not here shown) ina manner fully illustrated and described in one of its forms in myUnited States Patent No. 626,122, dated May 30, 1899, and need not befurther illustrated or described herein. Also located in this extension30 of the crank-case is the gear 41 for the water-pump, which mesheswith the cam-shaft gear 34. Also an idlergear 42 is located in thisextension and engages a magneto-gear 43, also located in the extension,and this latter gear being placed on the shaft of a magneto 44 of anydesired form for the purpose of providing an electric current forignition purposes.

From the foregoing it will be observed that all of the gears for thecooperating parts of the motor are located practically in the crank-caseor extension thereof, so that they are inclosed against dirt and dustand receive ample lubrication from the oil that is within the crank-caseand provides a compact arrangement of these gears. In order to permitready access to these gears for any desired purpose, the front end ofthe crankcase is removable, as shown.

As here shown, my invention is especially adapted for use inconnectionwithamultiplecylinder engine consisting of a plurality ofcylinders arranged longitudinally of the vehicle, the number ofcylinders 5 here illustrated being four.

The pipe 46, extending over the tops of the cylinders, is a portion ofthe water-line for cylinder-cooling purposes, and the member 47 in Fig.l is the projecting end of any suitable form of sparking plug forignition purposes.

By reference to Fig. 2 it will be noticed that the lower portion 3 ofthe crank-case extends downward between the drop frames or beams 2,which is a desirable arrangement.
